DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 267,040, dated November'7, 1882,

Application'filed June 27, 1882. (No model.)

To all whom it may concern:

Be it known that I, MORRIS W. TUCKER, of Sumner, in the county ofGratiot, State of Michigan, have invented a new and useful Improvementin Draft-Equalizers; and I declare the following to be a full, clear,and exact description of the same, such as will enable others skilled inthe art to which it pertains to I make and use it, reference beinghad tothe accompanying drawings, which form part of this specification.

This invention relates to improvements in that class of draft-equalizersfor which Letters Patent No. 236,196 were issued to me on the 4th day ofJanuary, 1881.

The object of my present invention is to provide means for tilting thearch and draftbar forward when the team is pulling apart and rearwardwhen the team crowds together, in order to produce a more equaldistribution of the draft. This objectI accomplish by the constructionillustrated in the accompanying drawings, in which- Figure l is aperspective view of the draftequalizing apparatusembodyingmyinvention,andhFig. 2 a detached perspective view of the are The letter A indicatesthe draft-bar; B, the straps for passing over the backs of the horses;(D,the draft-block; D, the equalizingchain; and D the outer chains,which pass from the ends of the draft-bar to the hames of the adjacenthorses. These parts are essentially the same as in my Letters Patentreferred to. In the use of that device it has been found that if bothhorses crowd out or pull apart at the same time the outer chains, D,become slack, and the draft is thereby thrown on the inner chains andupon the illner shoulders of the horses; and if the horses crowdtogether the inner chain becomes slack, and the draft is thrown on theouter chains and upon the outer shoulders of the horses.

clevis, F, or other device by which the rear draft-chain, F, isconnected with the vehicle.

The draft-block O is secured to the upward extension or arm of the archabove the clevis F, to receive the equalizing-chain D, which forwarduntil the equalizing-chain D is permitted to pass forward sufficientlyto take up the slack which would otherwise be caused in the outerchains, D, and thus the draft is equally distributed on both chains andupon the inner and outer shoulders of the horses. If, on the other hand,both horses crowd together or inward, the extension or arm or arch istilted rearward until the equalizing-chains D are permitted to passbackward sufficiently to take up the slack, and thereby bring the draftequally on both chains and upon the inner and outer shoulders of thehorses. The upward extension or arm of the arch also serves to shortenthe crock which was formerly necessary at the ends of the draft-bar, forthe reason that the location of the draftblock above the clevis causesthe bar to drop a. little below the line of draft, as indicated in myformer patent.

Having fully described my invention, what I claim is-- 1. In adraft-equalizer, the arch provided with the upward extension or arm forthe attachment of the draft-block, substantially as described.

2. Inadraft-equalizer,thecombination, with a draft-bar, of an archhaving an upward extension or arm, substantially as described.

3. Inadmit-equalizer,thecombination, with a draft-bar, of an arch havingan upward extension or arm, a suitable draft-block secured to saidextension or arm, and means for connecting the rear draft to theextension or arm, substantially as described,

In testimony whereof I sign this specification in the presence of twowitnesses.

MORRIS \V. TUCKER.
